<span class="sourceLineNo">034</span> * and transforms it to a byte stream using a specified charset encoding. The stream<a name="line.34"></a>
<span class="sourceLineNo">035</span> * is transformed using a {@link CharsetEncoder} object, guaranteeing that all charset<a name="line.35"></a>
<span class="sourceLineNo">036</span> * encodings supported by the JRE are handled correctly. In particular for charsets such as<a name="line.36"></a>
<span class="sourceLineNo">037</span> * UTF-16, the implementation ensures that one and only one byte order marker<a name="line.37"></a>
<span class="sourceLineNo">038</span> * is produced.<a name="line.38"></a>
<span class="sourceLineNo">039</span> * &lt;p&gt;<a name="line.39"></a>
<span class="sourceLineNo">040</span> * Since in general it is not possible to predict the number of characters to be read from the<a name="line.40"></a>
<span class="sourceLineNo">041</span> * {@link Reader} to satisfy a read request on the {@link ReaderInputStream}, all reads from<a name="line.41"></a>

<span class="sourceLineNo">043</span> * between the current position of the {@link Reader} and that of the {@link ReaderInputStream}.<a name="line.43"></a>
<span class="sourceLineNo">044</span> * This also implies that in general there is no need to wrap the underlying {@link Reader}<a name="line.44"></a>
<span class="sourceLineNo">045</span> * in a {@link java.io.BufferedReader}.<a name="line.45"></a>
<span class="sourceLineNo">046</span> * &lt;p&gt;<a name="line.46"></a>
<span class="sourceLineNo">047</span> * {@link ReaderInputStream} implements the inverse transformation of {@link java.io.InputStreamReader};<a name="line.47"></a>
<span class="sourceLineNo">048</span> * in the following example, reading from {@code in2} would return the same byte<a name="line.48"></a>
<span class="sourceLineNo">049</span> * sequence as reading from {@code in} (provided that the initial byte sequence is legal<a name="line.49"></a>

<span class="sourceLineNo">057</span> * {@link ReaderInputStream} implements the same transformation as {@link java.io.OutputStreamWriter},<a name="line.57"></a>
<span class="sourceLineNo">058</span> * except that the control flow is reversed: both classes transform a character stream<a name="line.58"></a>
<span class="sourceLineNo">059</span> * into a byte stream, but {@link java.io.OutputStreamWriter} pushes data to the underlying stream,<a name="line.59"></a>
<span class="sourceLineNo">060</span> * while {@link ReaderInputStream} pulls it from the underlying stream.<a name="line.60"></a>
<span class="sourceLineNo">061</span> * &lt;p&gt;<a name="line.61"></a>
<span class="sourceLineNo">062</span> * Note that while there are use cases where there is no alternative to using<a name="line.62"></a>
<span class="sourceLineNo">063</span> * this class, very often the need to use this class is an indication of a flaw<a name="line.63"></a>
<span class="sourceLineNo">064</span> * in the design of the code. This class is typically used in situations where an existing<a name="line.64"></a>
<span class="sourceLineNo">065</span> * API only accepts an {@link InputStream}, but where the most natural way to produce the data<a name="line.65"></a>
<span class="sourceLineNo">066</span> * is as a character stream, i.e. by providing a {@link Reader} instance. An example of a situation<a name="line.66"></a>
<span class="sourceLineNo">067</span> * where this problem may appear is when implementing the {@code javax.activation.DataSource}<a name="line.67"></a>

<span class="sourceLineNo">069</span> * &lt;p&gt;<a name="line.69"></a>
<span class="sourceLineNo">070</span> * Given the fact that the {@link Reader} class doesn't provide any way to predict whether the next<a name="line.70"></a>
<span class="sourceLineNo">071</span> * read operation will block or not, it is not possible to provide a meaningful<a name="line.71"></a>
<span class="sourceLineNo">072</span> * implementation of the {@link InputStream#available()} method. A call to this method<a name="line.72"></a>
<span class="sourceLineNo">073</span> * will always return 0. Also, this class doesn't support {@link InputStream#mark(int)}.<a name="line.73"></a>
